Testing the effect of deviance on similarity-based structure and certainty.
Hypothesis: We predict that as a new agent’s deviance from the group stereotype increases there will be a transition from group updating to subgroup formation to subtype formation. This will be reflected in participants’ similarity-rating derived dendrograms. Same as V3
Method changes:
only 25%/50%/75% deviancy
600 participants (increased from 300)
PNS scale added
Note: data for prediction values are corrected in R script due to coding error
